To (ZZZ whom it may concern Be it known that LFRANKLIN P. Sncnnrr, acitizen of the United States, and resident of Washington, in theDistrict of Columbia, have invented new and useful Improvements inHeadlights for Vehicles, of which the follow ice; is a specification.

My invention relates to head lights for vehicles, and pertains moreparticularly to the reflectors of such lainps.

The object of my invention is to produce a head light for automobiles,trolley cars and other vehicles from which the upwardly projecting raysare removed.

Another object of my invention is to pro duce a reflector for thehead-lamps of said character in which the sector of the reflectoradapted to project the rays from the burner upwardly and toward the sideon which another vehicle will approachtraveling in the oppositedirection is made blank or of nonrefiecti've-snrface, and a stillfurther object thereof is to produce a more simple, cheap and. etlicienthead light or" said character than. has heretofore been attained.

To these ends my invention includes the combination and arrangement ofcomponent parts to be hereinafter described and more particularlypointed out in the claim.

In the accompanying dr ngs in which like reference characters indicatesimilar parts, Figure l is a front view of my reflcotor, and Fig. 2 is ahorizontal sectional View of a head lamp embodying my invention.

Referring to the drawings, 1 indicates the case of a lamp having theglass lens 2 therein, the reflector 3 in the bac: thereof and the burner4 between the lens and the reilector. The general construction of thelamp he of any suitable type, and as same forms no part of my inventionwill not be more particularly described.

The reflector 3, as shown, is concave and circular in shape, and, eit'ept as hereinafter described, is of suitable material and polishedfinish adapted to project the rays of light from the burner dthrough thelens 2 on the opposite side of the burner.

Specification of Letters Patent.

Patented May 118, 1915.

Serial No. 859396.

For the purpose of removing the rays of light that would be projectedupwardly through the lens and serve no useful purpose to the driver ofthe vehicle on which the lamp is carried, and to avoid the of tensiveand blinding effect that such rays produce on the drivers of vehiclesapproaching from the opposite direction, I have rendered the lowersector 5 of the re- Hector 3 blank or non-reflective of light. Saidnon-reflective sector may be oil-set from a vertical line, as shown, toblank the rays projected. toward the inside of the road aiead to furtheravoid the oii'ensive glare on the opposite side of the road.

It will he apparent that the full efiicienc a headlight to illuminate aroad bed is no wise impaired by the removal of the upwardly projectedrays, and that safety of travel is assisted by the removal of theblinding glare from the eyes of persons within the range of theprojected light; and it will appreciated that my reflector thusdescribed may be varied in the details of its construction within a widerange without departing from the spirit and-scope of the claim.

ving thus described my invention, What I claim as new, and desire to besecured by Letters Patent, is

A reliector for vehicle lamps comprising a concave plate, a portion ofthe face of which is reflective of ight and the balance of which isnon-reflective, the reflective portion of which comprises a sectorextending from approximately the center of the plate to its outer edge,and the balance of which comprises a non-reflective sector of less thanone half the surface on the lower portion of the plate adapted toeliminate the upwardly projecting rays from the projected beam andretain the rays directed on the roadway, substantially as described.
